IO3Err:Training Error Status
This field should not be used for obtaining Training error status due to a
recent PCI Express Base Specification, Revision 1.0a Errata Dec 2003 to
remove training error.
UNCERRSTS[0] - Uncorrectable Error Status For ESI Port
This register identifies uncorrectable errors detected on ESI Port. If an error occurs and
is unmasked in the detect register (EMASK_UNCOR_PEX), the appropriate error bit will
be recorded in this register. If an error is recorded in the UNCERRSTS register and the
appropriate bit (along with the severity bit of the UNCERRSEV register) determines
which bit in the PEX_FAT_FERR, PEX_NF_COR_FERR, PEX_FAT_NERR,
PEX_NF_COR_NERR registers get recorded. These error log registers are described
starting from Section 3.8.12.24.
